Why Choose the ABB NFZ71E-22 Contactor Relay?
The ABB NFZ71E-22, product ID 1SBH136001R2271, is an 8-pole contactor relay designed for reliable switching of auxiliary and control circuits in industrial automation, machinery and electrical control systems. As part of the ABB NFZ contactor relay range, it combines a flexible electronic coil interface with a compact design suitable for modern control panels.
The NFZ71E-22 features seven normally open (NO) and one normally closed (NC) auxiliary contacts. Its electronic coil accepts a wide 48–130 V AC 50/60 Hz or 48–130 V DC control voltage, helping simplify component selection where different control voltages may be encountered. The relay also incorporates surge protection, reducing the need for an additional surge suppressor.
Designed for industrial control applications, the NFZ71E-22 supports direct control by suitable PLC outputs and is engineered to withstand control-voltage variations, short voltage dips and voltage sags. Screw terminals provide straightforward wiring, while its compact 86 × 45 × 110.5 mm dimensions make it suitable for installation in space-conscious electrical control assemblies.
